5 Key Differences Between Aluminium and uPVC Windows

When it comes to choosing aluminium vs uPVC windows for your home or building, two popular options that often come into consideration are aluminium and uPVC windows. Each material offers its own set of advantages and characteristics, making them suitable for different applications and preferences. To help you make an informed decision, let's explore five key differences between aluminium and uPVC windows:

Material Composition:

Aluminium Windows:

Aluminium windows are constructed from lightweight yet durable aluminium frames. Aluminium is naturally strong and resistant to corrosion, making it ideal for withstanding harsh weather conditions and providing long-lasting performance.

uPVC Windows:

uPVC, or unplasticized polyvinyl chloride, is a type of plastic material commonly used for window frames. uPVC windows are known for their affordability, versatility, and low maintenance requirements.

Aesthetic Appearance:

Aluminium Windows:

Aluminium frames offer a sleek and modern appearance, with slim sightlines that maximize the glass area and enhance visibility. They are available in a wide range of colors and finishes, allowing for customization to match the aesthetic of any property.

uPVC Windows:

uPVC frames tend to have a bulkier appearance compared to aluminium, with thicker sightlines that may reduce the amount of visible glass. While uPVC windows also come in various colors and finishes, they may not offer the same level of customization as aluminium frames.

Strength and Durability:

Aluminium Windows:

Aluminium is inherently strong and resistant to warping, rusting, and rotting. Aluminium frames can withstand extreme weather conditions, making them suitable for both residential and commercial applications.

uPVC Windows:

uPVC is durable and weather-resistant, but it may not be as strong as aluminium. uPVC frames can be prone to expansion and contraction with temperature changes, potentially affecting their long-term performance.

Energy Efficiency:

Aluminium Windows:

Traditionally, aluminium frames were not known for their energy efficiency due to their high thermal conductivity. However, modern aluminium windows often feature thermal breaks and insulating properties to improve energy efficiency and minimize heat transfer.

uPVC Windows:

uPVC frames are inherently more energy-efficient than aluminium frames, as uPVC is a poor conductor of heat. uPVC windows help to retain heat indoors during colder months and keep out heat during warmer months, contributing to overall energy savings.

Maintenance Requirements:

Aluminium Windows:

Aluminium frames require minimal maintenance and upkeep. They are resistant to rust, corrosion, and decay, and can be easily cleaned with soap and water.

uPVC Windows:

uPVC frames are also low maintenance and can be cleaned with soap and water. However, over time, uPVC frames may discolor or fade due to exposure to sunlight and harsh weather conditions.

In summary, while both aluminium and uPVC windows offer their own unique benefits, they differ in terms of material composition, aesthetic appearance, strength and durability, energy efficiency, and maintenance requirements. Ultimately, the choice between aluminium and uPVC windows will depend on your specific needs, preferences, and budget constraints. Consider consulting with a professional window installer to determine the best option for your home or building.
